In this paper
we proposed a novel coding scheme is proposed using wavelet-based CS framework for nature image. First
two-dimension discrete wavelet transform (DWT) is applied to a nature image for sparse representation. After multi-scale DWT
the low-frequency sub-band and high-frequency sub-bands are re-sampled separately. According to the statistical dependences among DWT coefficients
we allocate different measurements to low- and high-frequency component. Then
the measurements samples can be quantized. The quantize samples are entropy coded and forward correct coding (FEC). Finally
the compressed streams are transmitted. At the decoder
one can simply reconstruct the image via l1 minimization. Experimental results show that the proposed wavelet-based CS scheme achieves better compression performance against the relevant existing solutions.

There mainly is laser digital photofinishing technique and digital photofinishing technique based on LCD consisting of TFT and LCOS in the digital photofinishing field at the present time. The former have a good many merit such as wide color gamut
high processing rate
large output size and high brightness
but his cost is very high
his maintain technique being comparatively complex
that result in difficult use for people. The utilization ratio of the latter is low because of lower resolution and lower aperture ratio for LCD
but the digital photofinishing based on LCD have lower cost and higher utilization ration
being suitable for people's current standard of living. Considering above mentioned problem
a micro-motion exposure method based on PZT piezoelectric ceramics used in digital image photofinishing is presented. The two-dimension micro-motion exposure system consisting of PZT piezoelectric ceramics
LCD panel
polarizing film and spring strip is designed. By means of PZT piezoelectric ceramics the LCD panel is removed about the one half of the pixel size of the LCD panel for four times from the original place
at the same time imaging system is exposed four times at the printing paper. The software is used to control the time synchronization
the exposure time and motion range of the LCD panel. The system has advantages such as shorter response time than 0.1seconds
lesser motion error than 0.01 microns
high stability and repeatability. Experimental results show that the proposed micro-motion exposure method improve the picture brightness and enlarge output size
at the meantime reducing the cost of the system. 2009 SPIE.
